摘要：A spatial database is a database that store data that represents objects defined in a geometric space. Thispaper considers that objects are tagged with keyword and are embedded in a vector space. Due to growing data, NearestKeyword Set(NKS) queries are used in many applications. These queries are studied that retrieves the tightest groups ofpoints that contains a given set of keywords. Various methods for fast processing of queries are been studied.
